Overview
The Lambda CA400 5A is a versatile modular power supply from TDK-Lambda, engineered for industrial and control system applications. With input ratings of 100–230V, 47/63Hz, 7A maximum, this unit delivers up to 400W of regulated DC power. The Alpha 400W incorporates a modular design with interchangeable output modules that enable a single unit to provide power to devices with varying power requirements, making it an excellent choice for legacy machine retrofit and OEM integration.
